IRQ 7 and 15 on the PIC architecture are used for spurious interrupts. IRQ 7 could also be used for LPT connection, and IRQ 15 can be used for the secondary IDE channel. Therefore, we need to allow to install a real IRQ handler and check if a real IRQ was asserted. If so, we handle them in the usual way. A note on this fix - unregistering or registering a new IRQ handler after we already registered one in the spurious interrupt handler is not supported yet. |
